Chiral pesticides R/S-ethiproles(R/S-EPLs) have different biotoxicity. Due to the difficulty in the separation of chiral sulphur enantiomers, it is of great significance to study the selective recognition and separation of chiral sulphur enantiomers R/S-ethiproles. Based on DFT method, we theoretically designed a novel asymmetrical ligand of 4-amino-6-(9-[5-hydroxy-1H-indol-6-yl]-4,7-dimethoxy-1,10-phenanthrolin-2-yl)-1H-indol-5-ol (AHPIL). Then we further constructed the chiral-at-uranium complex, namely, Uranyl-AHPIL, to recognize and separat...
